UNITED STATES PATENT OFFICE GEORGE L. MOODY, OF NEW YORK, N. Y.

ANNULAR PETROLEUM-BURNER FOR HOT AIR, STEAM, ANI) vHYDl'iOCRBON FLUl-DS.

Specification forming part of Letters Patent No. 61,682, dated January29, 1867.

To whom' 'it may concern:

Be it known that I, GEORGE L. MOODY, ot' the city, county, and State ofNew York, have invented a new and useful Improvement for BurningHydrocarbons for Generating Steam by theheans of an An nularPetroleum-Burner and I do hereby declare the following to be a full andexact description ot' the same, reference being had to the accompanyingdrawings, which form a part thereof, and in each of which' like lettersrepresent like parts.

Figure 1 represents the outer appearanceof the burner alone disconnectedfrom the supplypipes and from the boiler. Fig. 2 represents thelongitudinal section ot the burner with the addition of a button, B B.`Fig. 3 represents another form of orifice for the discharge ofsuperheated steam in connection with the orices of discharge of the oiland of. heated air,-in which D D is a perforated hollowr re ceiver, fromwhich the apertures o o o o o discharge through it and into s3 s3.

The nature of my invention consists, irst, in the total and economicalcombustion of petroleum oil, or a hydrocarbon tluid under pressure, insuch a manner as to leave no rcsidunm, and make no smoke withoutsubjectvin g the hydrocarbon to a temperature which will volatilize it,or consume any portion of it before its arrival in a fire-box Orfurnace,where the oil is irst ignited with a torch or match, and heated air isforced through a concentric pipe which discharges under pressure closeto the oil-oritice. Superheated steam is at the saine time dischargedthrough-another concentric pipe close to this orifice, so' as to minglewith the oil or hydrocarbon. Gombustion takes place with some noise,arisingfrom a continuous series of light detonations.

This result is not so fully attained where the burner is straight.

The quantity of each of the elements is graduated either by anadjustable orifice or by stop-cocks in the supply-pipe, or by both.

The oil-orifice may be axial or exterior. Any of the orifices may beused for the discharge of either of the elements.

Theseburners maybe arranged to discharge their flame at any point insidethe` iirebox, and may be applied to locomotive or stationf ary boilers(as well as to the various purposes where an intense heat is required)by iirst tapping. the boiler with a thread to tit one on` the outs-ideofthe burner, or by putt-ing slierttubes through the boiler-plates andscrewing the pipe through this tube, which likewise acts as a brace.

In Fig. 2 of my drawings, a a represent the outer pipe; b b, the secondpipe, separated from a, a by the annular space s1 s.

c c represents a third concentric pipe, (sepia arated from b b by theannular space 82.82,) through which superheated steam is supplied to thespace s3 s3,whic li is a third annular space between the button-B B andthe continuation of the pipe c c.

B B represents a button used for making the steam-orifice annular.

d represents the pipewhich supplies the hy drocarbon to the space .9.1sl,- e, the pipe supplyinghot air to the space s2 s2.

f represents a nut working, bya thread, g, on the pipe a, attached tothe pipe b by the Arings h h, which prevents any but an arial motion onthe pipe b. -By turning this nutl the orifice vformed by a b isadjusted, opened, or

The concentric parallel motion 'of bis secured by the guides n n 'n andthe fixed ring k represents the packing; 1,.the follower, held in placeby m, on which a thread is cut.

To operate this burner, let on the oil through d. Ignite itin thefire-box or furnace.' Soon the hot-air blast (the air being heated fromwaste heat) may be applied, and shortly theV superheated steam. It'another boiler is near, vthe heated air and steam may be taken from thattire.

The amount of oil, hot air, and superheated steam may be regulated as isfound necessary. In Figs. 1 and 2 a thread is shown out upon the outsideof the pipe a a', for screwing through the outer and inner shells of theand making no smoke, 'substantially in the and oil or a hydrocarbon unidwith the admanner above set forth. `instable orifice, as a whole, andits applica 2.x The adjustable o rice through which the tionsubstantially in the manner and for the oil is discharged, male4substantially in the purposes herein mentioned.
